## Summary description

K-FLEX® SOLAR insulation tape by K-flex, size 3 mm thickness × 50 mm width × 15 m length. Designed for thermal insulation and protection of pipes, ducts and exterior surfaces in solar and HVAC installations. Provides a conformable, adhesive-backed insulating layer to reduce heat loss, protect against condensation and improve energy efficiency in building and solar thermal systems.

## Long description

K-FLEX® SOLAR insulation tape is a flexible, adhesive-backed thermal protection tape designed for pipes and exterior surfaces in solar and HVAC systems. With 3 mm thickness, 50 mm width and 15 m length, the tape provides a thin, conformable insulating layer that reduces heat loss, limits surface condensation and helps maintain system efficiency. The product is suitable for retrofit and new installations where a slim, easy-to-apply insulation solution is required.
Advantages
The tape combines a closed-cell elastomeric foam structure with a pressure-sensitive adhesive, providing good thermal resistance in a compact format and fast installation without mechanical fasteners. Its conformability allows it to follow curved and irregular surfaces, while the adhesive backing ensures a continuous insulating seal. The material resists moisture absorption and helps prevent corrosion under insulation when applied correctly.
Suitable for
Insulating small-diameter pipes and exposed tubing in solar thermal and HVAC systems
Sealing joints, elbows and flanges where full-section insulation is impractical
Surface protection on ducts, manifolds and equipment housings to reduce heat loss
Retrofit applications where space is limited and a thin insulating layer is required
Key specifications
Material type: closed-cell elastomeric foam
Thickness: 3 mm
Width: 50 mm
Length: 15 m
Backing: pressure-sensitive adhesive on one side for self-adhesion
Thermal performance: suitable for reducing conductive heat loss on small pipes and surfaces
Moisture resistance: low water absorption characteristic of closed-cell foam
Application temperature range: suitable for typical solar and HVAC operating conditions (follow manufacturer guidance for exact limits)
How to use
Prepare the surface by cleaning and drying the pipe or surface to remove dirt, oil and loose material. Measure and cut the required length of tape, then peel the release liner and press the adhesive side firmly against the substrate, ensuring full contact and avoiding gaps. Overlap tape edges or wrap with a slight tension on curved runs to achieve a continuous insulating layer. For longer runs or exposed locations, secure the tape ends and joints with compatible sealing tape or mechanical supports as needed.
Usage recommendations
Store rolls in a dry, shaded place away from direct sunlight and extreme temperatures. For best performance, apply at recommended ambient temperatures and avoid installing on wet or frozen surfaces. Inspect adhesive bonds and exposed edges periodically and repair any damaged areas to maintain thermal continuity and condensation protection.
